There will be some sort of confusion for interpreting idnabis-tables 
document.  I feel some classes marked as "No" should be investigated 
deeply.  As pointed by Erik, for Japanese, compatible characters 
(full-width/half-width) in range of U+FF01..5E and U+FF65..9F should 
be noted as "available in input", and CJK symbols in range of U+3005..07 
should be noted as "available as IDNs".
